This post was most recently updated on November 16th, 2020

Nioxin products are backed by over 30 years of dedicated independent research. In addition, you’ll be happy to know that Nioxin has the support of the Institute of Trichologists, the foremost professional association for the study and science of hair in the world. 

So, as we delve into reviewing Nioxin’s products, let’s start with a list of some of the causes of hair loss that Nioxin products help you to solve. They include:

  • Genetics 
  • Stress and trauma 
  • Nutrition and diet 
  • Health concerns or medication 
  • Environmental factors 

Now let’s dive right into the review.

What is Nioxin?

Nioxin is a hair care and scalp treatment system that was launched in the ‘80s by Eva Graham. After experiencing hair loss during her pregnancy, Eva made it her mission to help both men and women keep their hair full and healthy. Although the company was later bought by Procter and Gamble, Nioxin’s products are still used in salons around the world and by many individuals in their homes. 

Another interesting fact is that in 2017, hair stylists and clients voted for Nioxin and it won the Favorite Fine/Thinning Hair Line award at the 2017 Stylist Choice Awards for the 16th time in a row.

Nioxin Hair Products 

Nioxin has an array of products for thinning hair. If you’re looking for shampoos for thinning hair, thickening styling products to hair growth products, Nioxin’s got you covered. 

Treatments for hair thinning 

The Nioxin System kits are the most popular products by the Nioxin brand and we’ll look at them in detail. 

This particular set of Nioxin products is divided into 6 sets depending on the nature of your hair and comes in a 3D care system that contains:

  • Nioxin Clean Shampoo for thinning hair
  • Conditioners for hair thinning 
  • Scalp & hair leave-in treatments for hair thinning 

With so many Nioxin systems kits to choose from, how do you know which one is for you? We’ve broken down each system with a short summary to help you make that decision seamlessly depending on the nature of your hair: natural, colored, treated, and so on. 

Take a look.

Nioxin 3 Part System No.1

Nioxin System 1 is perfect for light thinning, non-colored hair. 

This product amplifies your hair texture and protects it against breakage. Because it is formulated as a hair thickening treatment, it gives you denser-looking hair and strengthens your hair, reducing breakage. 

Nioxin 3 Part System No. 2

Nioxin System 2 is perfect for progressed thinning, non-colored hair.

The Nioxin System Kit 2 is great if your hair is thinning and non-colored and you want it to be fuller thicker and resilient against damage and breakage. It also helps clean, optimize, and treat your hair and scalp. 

Nioxin 3 Part System No. 3

Nioxin System 3 is perfect for light thinning, colored hair.


This Nioxin kit leaves your colored hair denser-looking with vibrant color. Nioxin System 3 is great for removing follicle-clogging sebum, fatty acids, and environmental residues in your hair. It also leaves your hair moisturized and protected. 

This volumizing Nioxin System 1 regimen reduces hair loss that is caused by breakage and strengthens your hair, while refreshing the scalp and delivering a healthy shine to your natural hair with light thinning.Therefore, this product is perfect for you if you suffer from hair loss due to hair breakage, for example caused by environmental factors.

Nioxin 3 Part System No. 4

Nioxin System 4 is perfect for advanced thinning, colored hair. 


The Nioxin System 4 delivers thicker, fuller hair by removing fatty acids, follicle-clogging sebum, and environmental residues from your hair. Also, it provides you with moisture balance and color protection for your denser-looking hair. 

Nioxin 3 Part System No. 5

Nioxin System 5 Hair Care Kit

Nioxin System 5 is great for light thinning, chemically-treated, bleached, permed, or straightened hair. 

The Nioxin System 5 kit helps you get fuller-looking moisturized hair by amplifying your hair’s texture and restoring the moisture level while still providing protection to your colored hair. As with the System 4 kit, it removes fatty acids, follicle-clogging sebum, and environmental residue from your hair. 

Nioxin 3 Part System No. 6

Nioxin System 6 Hair Care Kit

Nioxin System 6 is great for progressed thinning, chemically-treated, bleached, permed, or straightened hair.

The Nioxin System 6 kit helps you get fuller-looking moisturized hair by amplifying your hair’s texture and restoring the moisture level while still providing protection to your colored hair. It also removes fatty acids, follicle-clogging sebum, and environmental residue from your hair.  

Please note that each shampoo works differently for each set depending on your hair type. The cleanser however removes dirt and debris that would otherwise block your hair follicles and actively removes follicle-clogging sebum that often contains the hormone DHT that affects hair growth. Therefore, if you’ve heard that the Nioxin cleanser also promotes hair growth, this is why. 

You can choose to buy the shampoo separately or buy the whole kit for your specific hair type.

Why Use Nioxin Hair Products?

Nioxin hair products are for anyone who has suffered hair loss or hair thinning and would like to try something that might help. We understand that experiencing hair loss is a frustrating experience but we believe that if you’re reading this, you’ve taken the brave step to do something about it. 

As John F. Kennedy says, “There are risks and costs to action. But they are far less than the long range risks of comfortable inaction.” Nothing is set in stone, and if your hair is thinning and you’d like to strengthen it, Nioxin hair products are for you. Whether it’s thinning locks or alopecia areata, these tested, tried, and trusted products are here for you. 

Some of the benefits that you’ll enjoy from using Nioxin hair products include:

  • Better blood circulation to your scalp that will allow essential nutrients and oxygen to nourish your scalp.
  • Reduced inflammation which is a red flag in autoimmune conditions such as alopecia
  • A dandruff-free scalp.
  • Blocking of DHT.
  • Healthy shiny hair promoted by the antibacterial and antifungal properties. 

How to use Nioxin?

Since Nioxin products are mostly centered on your scalp, it may be a good idea to treat your scalp like you do your face. This means extending the same care and attention that you give your face to your scalp. 

Here’s a 3-step process that you can use to treat your scalp.

  1. Cleanse

The first step is to clean your scalp using the minty-smelling shampoo to get rid of the excess sebum on your scalp. Fortunately, the shampoo lathers well so simply massaging it into your scalp from the roots for a minute or two should do the trick. 

2. Optimise 

Think of this second step as moisturizing your hair after a good wash. Apply a pea-sized amount of conditioner onto your mane and gently comb it paying special attention to the ends of your strands. After 2-3 minutes, and once you’re satisfied with the results, rinse. 

3. Treat

This last part is all about pampering. Use the Nioxin Scalp Treatment to pamper your scalp and protect it from external pollutants that may harm it. Divide your dried hair into desired sections and spray the treatment into your hair while gently combing with your fingers. There’s no need to rinse out the product. 

Nioxin Side Effects 

Does Nioxin have side effects? Yes. We’d be lying if we didn’t give you some forewarning about the side effects you might experience while using these Nioxin products. Although some are 

totally normal, some may catch you off guard. 

Because the Nioxin products contain so many ingredients, there’s a larger chance for allergic reactions. As mentioned in the products section, the shampoo lathers quite easily. A big reason for this is because of the detergents and sulphates it contains. These ingredients can irritate your scalp and cause itchiness, but you can easily overcome that by some simple home remedies

You may also be allergic to some of the ingredients so it’s important that you check the ingredients against your known allergies. Nonetheless, because the ingredients in Nioxin products are non-prescription and generally mild, you can be rest assured that severe reactions are rare. 

Some other side effects other than irritation include: 

  • Dry/brittle strands
  • Reddened scalp 
  • Cooling, tingling sensation 
  • Increased hair fall in initial stages (also known as hair detox so don’t freak out when this happens in the initial stages)

Unless you are allergic to any of the active ingredients, you shouldn’t worry about these Nioxin side effects as they are completely normal. However, if the side effects become too persistent, kindly consult a specialist. 

However, according to healthgrades, you should stop using the product and ask a doctor if you experience any of these very rare symptoms:

  • Unwanted facial hair growth 
  • Excessive scalp irritation and redness 
  • Chest pain, rapid heartbeat, faintness or dizziness 
  • Swelling hands and feet 
  • Sudden, unexplained weight gain 

Nonetheless, unless they are on the extreme side, these side effects are normal and a reflection that your scalp is getting used to the new treatment. 

Nioxin Alternatives

Some Nioxin alternatives for hair thinning include: 

Revivogen MD Bio-Cleansing Shampoo for Thinning Hair

Nioxin Before and After Pictures and Results 

Hair thinning and hair loss has a huge impact on our lives no matter what is causing it. Because hair plays a big part in our self-identity, seeing your hair change when you look in the mirror can affect your confidence levels. Therefore, seeing your hair improve and your bald patches disappear can boost your confidence. 

We’ve compiled some before and after pictures of Nioxin users from the Nioxin website as well as Amazon. Seeing the experiences and results of other users can give you a perspective on the Nioxin product.

What users say

After going through hundreds of reviews of the Nioxin product from both the website and the Amazon website, here are some of the common themes and feedback. 

  • The 3 System kits work best when used together as a whole because each product has its own job to do. 
  • Seeing results depends from person to person but on average most Nioxin users start seeing results after a couple of weeks of use. 
  • Users who have finer hair report that the Nioxin products cause breakages and hair to fall before regrowth happens. This means that if you have fine hair, it may be wise to be patient and to continue using the products even if you’re not getting the desired results. 
  • Some Nioxin users have become skeptical since P&G bought the company and added sodium laureth sulphate to the mix of ingredients. 

Although there are mixed reviews, the general consensus is that the Nioxin hair loss shampoo is very effective for thinning hair. 

Conclusion 

We hope that this article has provided you with sufficient information for you to make an informed decision about which Nioxin products is right for you.
